历年真题实战技巧（13） 2006年卫生类C Sleepwalking (梦游) 　　Not all sleep is the same every night. We experience some deep, quiet sleep and some active sleep, which is when dreams happen. You might think sleepwalking would happen during active sleep, but a person isnt physically active during active sleep. Sleepwalking usually happens in the first few hours of sleep in the stage called slow-wave or deep sleep. 　　Not all sleepwalkers actually walk. Some simply sit up or stand in bed or act like theyre awake when in fact, theyre asleep! Most, however, do get up and move around for a few seconds or for as long as half an hour. 　　Sleepwalkers eyes are open, but they dont see the same way they do when theyre awake and often think theyre in different rooms of the house or different places altogether. Sleepwalkers tend to go back to bed on their own and they wont remember it in the morning. 　　Researchers estimate that about 15% of kids sleepwalk regularly. Sleepwalking may run in families (在家族中世代相传) and sometimes occurs when a person is sick, has a fever, is not getting enough sleep, or is stressed (紧张). 　　If sleepwalking occurs frequently, every night or so, its a good idea for your mom or dad to take you to see your doctor. But occasional sleepwalking generally isnt something to worry about, although it may look funny or even scary (骇人的) for the people who see a sleepwalker in action. Although occasional sleepwalking isnt a big deal, its important, of course, that the person is kept safe. Precautions (预防措施) should be taken so the person is less likely to fall down, run into something, or walk out the front door while sleepwalking. 解题思路 文章标题——“梦游”。由于标题很短，信息量不足，故尽量多读些与中心有关的内容，“but”所在句子意思——“你可能认为梦游发生在睡眠活跃期，但是，一个人的睡眠活跃期并不意味着身体也活跃” 31．When does sleepwalking usually occur? 　　A During active sleep, 　　B During deep sleep. 　　C In the daytime.
